Hey guys, I'm having an issue getting my laptop's built in USB SD Card Reader to work. I bought it a few days ago and I can read its contents just fine when I'm on a liveCD, but on my actual Gentoo instalaltion, it hasn't really worked out for me.
On my kernel config, I have:

dmesg doesn't say anything relevant to the SD Card, it just mentions rtl8723au, which is my wireless card.
Yea, I'm pretty sure I'm running the right kernel, just double checked now and the modules I listed in the OP are on Y.

It doesn't really make a difference if I plug in an USB with the SD Card inserted, it reads just fine.
I do have CONFIG_USB_ANNOUNCE_NEW_DEVICES=y and it does work whenever I plug in my USB flashdrive or my mouse through the USB slot, but nothing when the SD card is inserted.

My mouse, flash drive, and USB headset are working just fine too.

CONFIG_BLK_DEV_SD is set to y

I actually didn't have all three XHCI, EHCI, UHCI built in/modularized (rather, I had some of them built-in or modularized, but not every single one of them), but I did so after reading your post. Still no change.

Ok if it works when the sd card is already inserted and then the USB is plugged in, but not when the media is inserted after USB is plugged in, it's a udisks issue - need to tell udisks/hal to poll the usb device... which is something I'm not sure how to do as it keeps changing..._________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed to be advocating?
